8.2 High Your boiler is struggling to keep its internal ignition flame lit, which prevents the main burner from starting and means you will currently have no hot water or heating.
8.3 High Your boiler is failing to keep its small starter flame lit, which prevents the main system from firing up to provide you with heating or hot water.
8.4 High Your boiler is failing to keep its internal pilot flame lit, which means it cannot safely ignite the main burner to provide heat or hot water.
8.4.1 High Your boiler is failing to ignite the flame needed to produce heat or hot water, meaning it has currently stopped working.
8.4.2 High Your boiler is struggling to keep the flame lit while you are trying to use hot water, causing it to cut out during use.
8.5 High Your boiler is currently unable to ignite its main flame, meaning it cannot produce any hot water or heating for your home.
8.6 Emergency The internal valve used to control your boiler's gas supply is sticking, which is preventing the system from igniting properly.
8.7 Medium Your boiler is struggling to heat the water to the required temperature, likely due to a sensor reading issue or a flow problem.
8.8 Emergency Your boiler has detected that the main gas control knob or internal valve is not moving or operating as it should, which is preventing the boiler from firing up safely.
8.9 Emergency Your boiler is not burning fuel correctly, which is causing dangerous soot buildup and indicates a significant risk of carbon monoxide production.
8.10 Emergency Your boiler is failing to shut off the flame when it should, which means it will continue to heat your water or radiators indefinitely.
8.11 Emergency Your boiler is not burning fuel correctly, which is causing soot buildup and indicates a serious issue with the combustion process.
8.12 High Your boiler has stopped working because the water pressure inside the heating system has dropped too low.
8.13 Medium Your boiler is struggling because it has detected air or built-up debris circulating inside it, causing loud banging or kettling noises.
8.14 High Your boiler's internal air blower is struggling or vibrating, which can lead to it failing to clear exhaust fumes properly.
8.15 High Your boiler has stopped working because the water pressure inside the heating system has dropped too low to operate safely.
BUBNEB STAYS ON Emergency Your boiler is failing to light properly because it cannot correctly detect or control the flow of gas, which may cause it to keep trying to fire up when it shouldn't.
EXPLOSIVE IGNITION Emergency Your boiler is struggling to light smoothly, resulting in a small mini-explosion inside the unit when it finally fires up, which can damage your internal components.
GAS CONTROL TAP STIFF (USER’S) Medium The dial you use to turn your heating or hot water on is stuck because the internal lubricant has hardened or the knob was not put back together properly.
HEATING BODY NOISE Medium Your boiler is making loud banging or kettling noises because the internal components are struggling to process heat due to a buildup of mineral deposits or restricted water flow.
INSUFFICIENT WATER FLOW High Your boiler is struggling to detect enough water flowing through it to safely start your hot water or heating.
LOW WATER TEMPERATURE High Your boiler is failing to heat your water properly because it is struggling to get enough gas or manage the water flow effectively.
MAIN BURNER DOES NOT LIGHT High Your boiler is failing to ignite the main flame, which means you currently have no heating or hot water because the system cannot produce heat safely.
PILOT FLAME DOES NOT LIGHT High Your boiler is failing to ignite because it cannot start the initial pilot flame required to begin the heating process.
PILOT WILL NOT STAY ALIGHT Emergency Your boiler is failing to keep its small pilot flame lit, which prevents the main heating system from starting up safely.
POOR PILOT FLAME High Your boiler is struggling to keep its ignition flame lit, which prevents the main burner from starting and stops your heating and hot water from working.
Red indicator - Lock out / flame failure High Your boiler has failed to light the flame, so it has safely shut itself down to prevent gas from building up.
UNSTABLE FLAMES Emergency Your boiler is struggling to keep its internal flame lit steadily, which means it cannot safely or reliably provide you with hot water or heating.
YELLOW FLAMES / SOOT FORMED Emergency Your boiler is not burning fuel correctly, which is creating dangerous soot and could potentially release harmful carbon monoxide into your home.
